当一个不相关的刺激特征与一个不正确的反应（冲突条件）相关联时，选择反应时间任务的表现会恶化。在冲突频率增加的情况下，这种干扰效应会减少。尽管认知控制模型解释了冲突相关的注意力集中在目标刺激维度上的这种调节，但这种效应可能反映了特定刺激集合或刺激特征-反应随因的实践。使用埃里克森侧卫任务，我们解构了冲突试验的频率和特定刺激组合的频率（即目标侧卫连词）。在实验1和2中，侧卫干扰与冲突试验的频率呈负相关，与特定目标-侧卫连词的练习无关，因此对刺激集合学习的解释存在争议。然而，在实验3中，侧翼干扰减少了特定的侧翼刺激，主要发生在冲突试验中。综上所述，这些发现与侧侧特异性注意调整或联想侧侧反应启动一致。
Performance in choice reaction time tasks deteriorates when an irrelevant stimulus feature is associated with an incorrect response (conflict condition). Such interference effects are reduced under conditions of increased conflict-frequency. Although models of cognitive control account for this modulation in terms of conflict-related attentional focusing on the target stimulus dimension, it is possible that the effect reflects practice with specific stimulus ensembles or stimulus feature-response contingencies. Using an Eriksen flanker task, we deconfounded the frequency of conflict trials and the frequency of specific stimulus ensembles (i.e., target-flanker conjunctions). In Experiments 1 and 2, flanker interference varied inversely with the frequency of conflict trials, irrespective of practice with specific target-flanker conjunctions, thereby disputing a stimulus ensemble learning account. In Experiment 3, however, flanker interference was reduced for specific flanker stimuli which occurred predominantly in conflict trials. Taken together, the findings are consistent with flanker-specific attentional adjustment or associative flanker-response priming.
